|Richard Weller: Could the sun be good for your heart? - TED.com|
Our bodies get Vitamin D from the sun, but as dermatologist Richard Weller suggests, sunlight may confer another surprising benefit too. New research by his team shows that nitric oxide, a chemical transmitter stored in huge reserves in the skin, can be released by UV light, to great benefit for blood pressure and the cardiovascular system. What does it mean? Well, it might begin to explain why Scots get sick more than Australians ...
